I let the phone charge all night. In the morning I turned it on and it powered up but turned off immdiately. I tried repeatedly to power it up and the light on the key pad blinked but nothing showed on the screan. Now nothing happends at all when trying to power up. The phone is only two weeks old.
Bring your phone back to wherever you bought it from to have it checked. It could be as simple as a battery issue or something really wrong with your phone. Hopefully you can have it repaired or replaced with a new one.
